Hi Michael & David,

The above is good advice.

Also, there is a temporary feature in place activated by the variable
"mnc_filefreq" within the data.mnc file.  Basically, what it does is
allow the user to specify an overall frequency (in terms of model time)
that MNC files should be created.  Currently, this frequency is only set
on a global (all mnc output files) basis using a simple bit of code in
FORWARD_STEP():

  IF (DIFFERENT_MULTIPLE(mnc_filefreq,myTime,deltaTClock)) THEN
     ...create new MNC output files...
  ENDIF

and it should do most of what you want.  Although, it still doesn't let
you write one-variable-per-file.
